Sensor and signal collecting and processing system for wushu free combat electronic protector

Abstract

The invention discloses a sensor for a wushu free combat electronic protector. The sensor comprises a piezoelectric film layer, wherein two pressure-sensitive films are clamped in the piezoelectric film layer; a silver nano-film layer for reducing the resistivity is also arranged between the two pressure-sensitive films; buffer layers are arranged on the upper surface and the lower surface of the piezoelectric film layer; a vacuum filling layer is arranged between each buffer layer and the piezoelectric film layer; a flexible shielding layer coating the whole piezoelectric film layer is arranged on the outer surface, far away from the piezoelectric film layer, of each buffer layer. The invention further discloses a signal collecting and processing system for the wushu free combat electronic protector; and the signal collecting and processing system comprises a sensor module, a circuit conditioning module, a digital-to-analogue conversion module, a signal judgment module, a wireless transmitting module and a wireless receiving module. The sensor is sensitive in sensing, is capable of sensing a pressure signal in an omnibearing manner, and is not easy to bend; meanwhile, according to the signal collecting and processing system, the fairness and the objectivity of the game are ensured, the requirements of free combat action techniques are improved and the competitiveness is indirectly improved.

Description

technical field [0001] The invention relates to a data processing technology, in particular to a sensor and a signal acquisition and processing system of a Wushu Sanda electronic protective gear. Background technique [0002] In the era of modern information data, signal transmission has become increasingly mature, but compared with the field of martial arts, there is no precedent for using sensors to process signal transmission. Due to a little mistake in the judging process of Taekwondo and Sanda competitions, it is likely to affect the results of the competition. A large deviation is caused, and the referee alone is not enough to ensure the fairness, openness and justice of the game. [0003] In the 2015 Xi'an University of Posts and Telecommunications master's thesis on the design and research of Sanda electronic protective gear, the information collection, transmission and processing system was adopted; It is not complete enough, and the sensor is easy to bend and defo...

[0002] In the era of modern information data, signal transmission has become increasingly mature, but compared with the field of martial arts, there is no precedent for using sensors to process signal transmission. Due to a little mistake in the judging process of Taekwondo and Sanda competitions, it is likely to affect the results of the competition. Cause a lot of deviation, the referee alone is not enough to ensure the fairness, openness and justice of the game

[0003] In the 2015 Xi'an University of Posts and Telecommunications master's thesis on the design and research of Sanda electronic protective gear, the information collection, transmission and processing system was adopted; It is not complete enough, and the sensor is easy to bend and deform, resulting in a further drop in sensing sensitivity; the signal transmission speed is slow, which cannot be applied to fast-paced Sanda competitions, and the transmitted signal is not screened and judged, which may easily cause errors in signal transmission. cause misjudgment; at the same time, the centralized processing of the signal is not perfect enough, it is easy to cause signal interference, make the transmission of the signal disorder, and cause cross interference in the signal that is finally transmitted to the terminal for data processing
